Aquiloni sottomarini che copiano gli skilift per catturare energia dalle correnti marine? Il progetto cableKites dell'Università di Monaco funziona: test positivi nel canale Isar a 0,6 m/s. Gli aquiloni "volano" sott'acqua raggiungendo 1,5 m/s, mille volte più compatti di un'ala eolica. Sistema modulare, costi ridotti, installazione semplice. L'Europa punta a 40 GWh/anno entro il 2050.

Live Train Departure Screens Keep You Abreast of Transit Developments
If you want to know when the train is coming, you could pull up a webpage on your phone, or walk all the way to the station to look at the displays there. Or, like [eastfamilyreddish], you could build a neat little train info display to decorate your desktop instead.
The build is based on the work of [gadec-uk]—who developed a train information display some time ago. It’s based around an ESP32 D1 Mini, paired with a 256 x 64 OLED screen to display relevant train information. It accesses a National Rail API for train status information—known as the Darwin LDBWS (Live Departure Board Webservice). Configuration is via a web GUI hosted by the ESP32 itself.
[eastfamilyreddish] took the concept further by adapting this hardware into a more pleasing form. The ESP32 and OLED screen are built into a neat little hanging sign setup that apes one you might expect to see at a real railway station. You might expect that 3D printing was involved, but instead, this was achieved with lasercut parts and resin casting to create something with a beautiful finish. They even went so far as to include a wireless phone charging module in the base, making the device extra useful to really earn its place on the desktop.
The fact is, around these parts we love both trains and the displays you find around them. If you’ve got a railway-adjacent project, or you’ve just built your own awesome railway, don’t hesitate to let us know on the tipsline!

This week my new PC arrived and I am trying to move over. For me, moving form one PC to the next is like moving a whole house... Going to take me a while to be productive again, especially since we have a new rentee! #gamedev #indiegame #kittycat

@benjistokman @hipsterelectron what happens if you give it a regular color photo and tell it the color count is 32?

Ooh, Slint can have almost automatic native look and feel via a build time option and light/dark modes (if you do things right in terms of styling custom components, which I mostly did not, but I can fix it pretty easily). Cupertino (Apple) style doesn't work for some reason...text is invisible. But, I don't have a Mac to build on, anyway, so that's a problem for another day.

@benjistokman @hipsterelectron holy smokes this looks great :O

@benjistokman @hipsterelectron I'm guessing you most likely want a perceptual color space like oklab or cielab.
The math involved is very fiddly and easy to get wrong, but the CSS spec has useful reference examples https://www.w3.org/TR/css-color-4/#color-conversion-code
You can also copy my notes https://github.com/Aeva/mollytime/blob/f4fe01f4ca979a0d24a3e7a11f6a5b4049cb3ea3/src/colors.cpp#L349 (my re-implementation of the math outlined in the above CSS spec)

Sbriciolata, giornata intensissima, e grata di tutto. Ora sono troppo stanca ma domani voglio prendermi un po' di tempo per scrivere Happy🦋
Intanto un pensiero lo lascio anche qui: grata del freddo sul naso e di poter rientrare in una casa calda che mi concede il lusso di apprezzare l'inverno.

@stefano Sure.
I was just lamenting on myself, I was almost going to get that fun contract with clear agreements, aced the interviews and then lost of signal, later I learned they closed the role.I wonder if we shouldn't at least charge for this, cause it's "work" and lack of respect at the same time.
